  • Publication number: 20060254523
    Abstract: A milking parlor has a holding gate and a parallel spaced individually loaded-occupied-unloaded milking stall with an operator pit located intermediate the holding gate and the milking stall. The operator pit can be recessed from the holding gate and the milking stall, wherein a bridge or a bridge cart selectively connects a holding gate to an unoccupied milking stall. A robotic or human operator can function from the operator pit to implement the milking process.

  • Patent number: 7055458
    Abstract: A milking parlor for presenting an animal to be milked rearwardly loads the animal into a milking stall through an ingress/egress gate and forwardly unloads the animal from the milking stall through the same ingress/egress gate to pass along a unique exit path to a released area.

  • Patent number: 6814026
    Abstract: A milking parlor having a plurality of translatable shuttle stalls allows for presentation of animals to be milked and corresponding release of the animals, independent of the milking status of additional animals. The shuttle stalls can be disposed in a herringbone or perpendicular orientation with respect to a corresponding operator pit, wherein the operator pit can accommodate human or robotic devices for implementing the milking process.

  • Patent number: 6779484
    Abstract: A milking system including apparatus and a method for facilitating the milking of a large number of animals in a milking parlor. Milking stalls in the parlor are arranged to provide a one way-path of travel through the parlor with a controlled entry and exit to facilitate pre- and post-milking treatment of the animals. The milking stalls are separated by an operator's pit. A platform or person mover disposed in the pit carries an operator from one milking stall to another wherein the proximity of a working side of the platform to the stalls allows the operator to have direct access to an animal without leaving the platform. Movement of the platform to a given stall is controlled by a controller acting responsive to sensors that indicate the occurrence of an event at the given stall requiring the operator's attention.

  • Publication number: 20020185071
    Abstract: The present invention provides an apparatus for automatically cleaning a teat of an animal, such as a dairy cow. The apparatus generally includes a first housing having a longitudinal axis and an interior wall defining a teat cleaning compartment, a motor (or other powering device)operatively coupled to the first housing for imparting rotary motion thereto about its longitudinal axis, and a first set of bristles engaged with the interior wall and extending radially inward therefrom, wherein the rotary motion imparted to the first housing is translated to the first set of bristles. The apparatus further includes a second housing concentrically positioned around the first housing that includes a cleaning fluid inlet nozzle positioned in fluid communication with a cleaning fluid conduit, and a cleaning fluid discharge nozzle.

  • Patent number: 5960736
    Abstract: A vacuum control for milking systems includes a vacuum pump driven by an electric motor which is activated by a variable frequency drive (VFD). The VFD is controlled during a milking phase by plc programmable controller and a proportional/integral (PI) controller which respond to a vacuum feedback sensor connected to the milking system. The plc controller differentiates between milk and wash phases and also provides a fixed preset speed control for a washing phase for the milking system. The integrator interfaces between a milk/wash controller and the plc.

  • Patent number: 5284180
    Abstract: A low-energy-consuming apparatus and method for controlling vacuum levels in machine milking and other vacuum systems subject to air leakage utilizes in combination a high vacuum reserve, a low-vacuum end (pipelines), a dual vacuum controller positioned between the high-vacuum reserve and the low-vacuum end and an adjustable speed drive (ASD) motor on a vacuum pump to regulate the delivered air to match the air usage in the low-vacuum end. The dual vacuum controller senses vacuum disturbances in the low-vacuum end and adjusts the flow rate of air from the low-vacuum end to the high-vacuum reserve rather than using external air makeup, thus providing a controlled vacuum with minimum pressure variance and energy input. Energy savings and demand reduction of about 50 percent (50%) during milking are realized under the new system.
